The Heartbeat on Dark Side of the Moon: Alan Parsons’ Own Pulse, Mic’d Directly on His Chest

The iconic heartbeat that opens and closes The Dark Side of the Moon is real — it’s engineer Alan Parsons’ own. He recorded himself lying down with a Shure SM58 dynamic microphone pressed directly against his bare chest, just over his heart.
